The best man speech is typically the best man's time in the spotlight to tell an embarrassing and funny story about the groom. What sets a good best man's speech apart from a bad one is having an element of emotion and sentimentality to it. Yeah, all youngsters are immature and do stupid and illegal things leading to waking up one morning in Tijuana, but this speech comes from the groom's best friend, on during the time when the groom is about to make the largest commitment of his life. So there should be a bit of emotion and seriousness in the speech. And classic best man speeches have all these positive qualities and are appreciated by all.
Giving best man wedding speeches is an art and you need to master it as fast as you can and for that you need to give some time and effort. As soon as you become familiar with your speech you will gain confidence to deliver it no matter how big the audience is or if you are giving a traditional best man speech or a creative one (the ones where the best man has some slide shows or have some play-acting involved). I hope you got the idea.
